ILGNETIC. SANDING DEVICE FOR MOTOR-VEHICLES.

Specification of Letters Patent. 7 Patented Feb. 19, 1918.

Application filed June '27, 1917. Serial No. 177,352.

To all whom it may concern:

Be it known that I, ELDRIGE V. McCUL- LOCH, a citizen of the UnitedStates, residing at Kansas City, in the county of Jackson and State ofMissouri, have invented new and-useful Improvements in Magnetic SandingDevices for Motor-Vehicles, of which the following is a specificationThis invention relates to a sanding device which may be ap lied to motorvehicles and employed to sand the roadway in advance of the wheels ofthevehicle.

The primary object of the invention is to provide an electricallyoperated device for this purpose which may be applied to any of thetypes of motor vehicles now in common use, without altering theconstruction thereof, or. requiring the services of a skilled mechanicfor the application of the device.

Another object of the invention is to provide a device of this characterwhich will require comparatively few parts, thus obviating thelikelihood of the device getting out of order while in use.

With these and other objects in view,'the invention resides in the novelcombinationand arrangement of parts, which will be hereinafter describedand particularlypointed out in the claims.

The preferred embodiment of the-invention has been illustrated in theaccompanying drawing, although no restriction is necessarily made to theprecise details of construction therein shown, as changes, alterations,and modifications, within the scope of the claims may be resorted towhen desired.

In the drawing:

Figure 1 is a view in side elevation of a. portion of a motor vehicle towhich isshown, applied the improved sanding device, the electricallyoperated valves forming a part thereof being shown in normal position infull lines and in dotted lines in position to ermit the sand within thesand box to be discharged upon the roadway in advance of the rear wheelsof the vehicle.

Fig. 2 is a top lan view of the sanding device, the valves orming a partthereof being shown underlyin a portion, of the foot boards of an automoile.

Fig. 3 is a vertical transverse section on the line 3--3 of Fig. 1, thesand box being shown in section.

Fig. 4 is a longitudinal sectional view through a portion of. one of thedischarge pipes on the sand box and the valve into which the pipeextends.

Fig. 5 1s a section on the line 5-5 of Fig. 4..

Like characters of reference denote corresponding parts throughout theseveral views inthe drawing. I

Referring now to the drawing in detail,

the letter A designates a portion of a motor vehicle wherein the body 10is mounted upon the rear wheels 11 in the usual manner, with the body 10having connected therewith? foot-boards l2 and a dash 13.

Mounted beneath the, body 10 in any suitable manner in advance of thewheels '11 are a pair of solenoids arranged in anormally open electriccircuit 15 which may be closed by a switch 16 mounted upon the dash 13in convenient reach of the operator ofthe machine.

A sand box 17 is arranged within the body 10, preferably beneath therear seat of the motor vehicle and is provided with a bottom 18 whichinclines in opposite directions from the central portion'of the boxtoward its ends to provide within the box, a pair of hoppers 19 whichempty into downwardly extending discharge pipes 20 provided/at theirlower ends with horizontally extending offset ortions 21 interposedbetween the rear whee s 11 of the vehicle and the solenoids 14.

cuit 15 is closed, the valves 22 may be turned in the bearings 23 to aposition in which the channel in a nozzle 25 on the valves will registerwith a discharge opening 26 in the ofi'set portion of the discharge pipewhich extends within the valve.

The other end of the actuating bar 24 has connected therewith and withthe foot-board beneath which the valve .is'arrangeiacoiled contractilespring 27 which when the switch is operated to break the circuit 15,turns the valve 22 in the bearing v23 to a. position in which thechannel in the nozzleon the valve is out of registration with thedischar e' opening 26 in the offset portion of the (11S.-v

charge pipe, thereby interrupting the discharge of sand from the boxupon the roaddrawing and the operator of the machine desires to sand theroadway in advance of the rear wheels of the vehicle, the switch uponthe dash is operated to close the circuit 15, thus causing the solenoidsto turn the valve and swing the nozzles thereon in a downward direction,so that the sand within the box will be discharged upon the roadway inadvance of, the wheels.

When the sanding of the roadwapis no longer necessary, the circuit .15is roken and the springs 27 rock the valves in the reverse direction,and cause the nozzles thereon to assume their normal position in a planeparallel to the foot-boards 12, thus cutting ofi" the discharge of sandupon the roadway.

.From thefore oing description, taken in connection with-t eaccompanying drawing, it is at once apparent that an electricallyoperated sanding device for motor vehicles has been provided, whereinthe nozzles for discharging sand upon the roadway in advance of the rearwheels of the vehicle are normally maintained in an out of the wayposition beneath the foot-boards of themachine.

Having thus described the invention, what is claimed as new, is: 1

1. In a device of the class described, a

source of sand supply, discharge pipes leading therefrom, valves intowhlch said pipes extend controlling the discharge of sand therefromyieldably held against turning movement, and electrical means forturning said valves.

2. In a device of the class described, a source of sand supply,discharge pipes leading therefrom having offset gpsigsions at theirlower ends provided with harge openings, valves into which said ofisetportions extend controlling the discharge of sand from said openingsyieldably held against turning movement, bars adjustably-mounted on saidvalves, and electrical means for turning said valves connected with thebars.

3. In a device of the class described, a sand box having a plurality ofhoppers therein, discharge pipes leadmg from said ho pers havin offsetportions at their lower en s provide with discharge openings, valvesinto which said ofiset portions extend mounted for rockin movement,nozzles on said valves to register with the discharge openings in saidoflset portions when the valves are rocked in one direction, springsconnected with the bars normall holding said nozzles out of registrationwit the discharge openings in said offset portions, and electrical meansfor causing said nozzles to register with the o enings in said ofisetportions includin so enoids having cores pivotally connecte with saidbars.
